App Usage #

Application usage stats for Android only. Note that the stats are only precise down to a daily basis. This is a limitation from Google's implementation.
Install #
Add app_usage as a dependency in pubspec.yaml.
For help on adding as a dependency, view the documentation.
Android #

Note: Requires API level 21 as a minimum.

I.e. you need to set the min SDK version inside the android/app/build.gradle:
minSdkVersion 21

You need to add the following package to the manifest namespace in AndroidManifest.xml:
xmlns:tools="http://schemas.android.com/tools"

as well as the following permissions to the manifest:
<uses-permission
android:name="android.permission.PACKAGE_USAGE_STATS"
tools:ignore="ProtectedPermissions" />

Below is an example of how the start of your manifest should look in the end
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="YOUR_PACKAGE_NAME_HERE"
xmlns:tools="http://schemas.android.com/tools">

<uses-permission
android:name="android.permission.PACKAGE_USAGE_STATS"
tools:ignore="ProtectedPermissions"/>

Usage #
The AppUsage class works as a singleton and you get app usage statistics by calling:
AppUsage().getAppUsage(startDate, endDate)

A larger example (from the example app) could look like:
void getUsageStats() async {
try {
DateTime endDate = DateTime.now();
DateTime startDate = endDate.subtract(Duration(hours: 1));
List<AppUsageInfo> infoList =
await AppUsage().getAppUsage(startDate, endDate);
setState(() => _infos = infoList);

for (var info in infoList) {
print(info.toString());
}
} on AppUsageException catch (exception) {
print(exception);
}
}

Each AppUsageInfo object has the following public fields:
/// The name of the application
String get appName => _appName;

/// The name of the application package
String get packageName => _packageName;

/// The amount of time the application has been used
/// in the specified interval
Duration get usage => _usage;

/// The start of the interval
DateTime get startDate => _startDate;

/// The end of the interval
DateTime get endDate => _endDate;

/// Last time app was in foreground
DateTime get lastForeground => _lastForeground;

Example app #
The example app shows how to use the plugin.
The first screen will ask for permission to view usage stats. Tap on your application and allow it to access usage information. Then you can "download" app usage stats by pressing the arrow button.
